CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation application of U.S. patentapplication Ser. No. 12/718,751, entitled “Binocular Apparatus andSystem”, to Robert W. Spaller, filed on Mar. 5, 2010, and thespecification and claims thereof are incorporated herein by reference.

BACKGROUND OF THE INVENTION

1. Field of the Invention (Technical Field)

The present invention relates to the field of binocular viewing systems.

2. Description of Related Art

Head mounted image displays (e.g. helmets, goggles, and eyeglassesincorporating miniature displays) and other compact display systemswhich provide data in alphanumeric, video, or graphic form haveapplications in avionics, medicine, entertainment, and wearablecomputers, as well as numerous other fields. There are three principaltypes of prior art head mounted display systems: “see-through systems,”in which the displayed electronic image is combined with the ambientimagery so that the user can see both images; “see-around systems” inwhich the displayed image occludes a part of the ambient imagery; and“full-immersion systems” in which the entire ambient image is blocked,so that the user sees only the electronically generated image. All threetypes of systems use various means, including lenses and the like, toproject the image into the viewer's eyes.

The simplest systems are of the see-around type in which the electronicdisplay is provided with one or more lenses and suspended in front ofthe user's eyes. A principal limitation of the device is that thedisplay and optical system must be moved with respect to the head, orthe head must be moved, to enable the user to see ambient imagery in theoccluded field. A significant part of the occlusion results from thesupporting structure and housing, as well as from the display itself. Asecond limitation of such devices is that the device is suspended fromthe head (or helmet, strap or other support borne by the head), so thatthe mass of apparatus adds an undesirable weight and/or torque to thehead. A third limitation of the device is that position of the exitpupil of the optical system cannot be fixed accurately, meaning that theexit pupil of the optical system must be large enough to accommodatevarious motions of the device that occur during use.

Full-immersion systems have many of the same limitations as see-aroundsystems. The head mounted system must be removed to view any ambientimagery. Typically, the systems comprise displays and lens systemssimilar to the see-around display, or comprise a display, lens systemand reflective screen. These systems involve high weight, torque andvolume. Full-immersion systems often cannot be safely used in manypublic environments.

See-through systems involve the most complex optical designs. Generally,the see-through system comprises a display, lens system, and viewingscreen or combiner. All of the limitations of the see-around display areshared by the see-through display, except for the need to remove thehead-mounted system to see ambient images. However, for this benefit, itis necessary to add further optical components, thus increasing theweight, complexity and cost of the system. See-through systems oftenoffer a lower quality viewing experience for users wanting to focus themajority of their attention on the content displayed.

All three of the above head mounted display types have the furtherlimitation of requiring that the optical systems be mounted in goggles,helmets, strap-on bands, unusually bulky wearable device enclosureshaving large visors and the like, rather than more conventional opticalsupports. This limitation requires users to become accustomed to wearingsuch devices, as well as making the user very conspicuous when wearingsuch a device.

Conventional binocular image display devices use a large cross sectionalarea or flexible joints of the head mounting devise to limit momentloading on the binocular optics and distortion of the alignment of theoptics and micro displays that can result from user forces. The bulk andunusual shapes often do not appeal to users.

Thus, there is a need for a device that overcomes the above and otherdisadvantages.

DETAILED DESCRIPTION OF THE INVENTION

The disclosed binocular display system among its various embodimentsprovides minimum occlusion of the user's field of vision such that theoccluded area is primarily filled with the image size displayed to theuser in a specific embodiment of the invention. The non-occluded fieldof vision remains available for environmental awareness of the user. Inone embodiment, the field of view is about 28°, but can range from 10°to 50°. In one embodiment, the total occluded area may be about 33°, butcan range from 10° to 45°.

The minimal height, depth, and width enabled by the disclosed binoculardisplay system allow the unit to be hidden behind a large variety ofsunglass or eyeglass styles. The ability of the disclosed binocularsystem to fit behind many consumer eyeglass styles allows broader marketacceptance for wearable binocular displays. The use of eyeglasses suchas sunglasses with the invention minimizes glare from the non-occludedfield of vision and enhance the viewing experience of the displaycontent.

FIG. 1 shows a top sectional view of the disclosed binocular display 10.The display comprises a body 14. Attached to the body 14 are a firstmirror 18 and a second mirror 22. Covering the first and second mirrors18, 22 respectively is a first mirror cover 26 and a second mirror cover30. A first micro display 34 and second micro display 38 are attached tothe body 14. Some micro displays that may be used with the disclosedinvention, include, but are not limited to: backlit LCD styles fromKopin, model KCD-VDCF-AA; OLED style from MicroOLED; OLED style fromeMagin. The disclosed invention may include micro displays developed inthe future. More micro-display companies and technologies are bound toappear. A first backlight 42 and second backlight 46 are also attachedto the body 14. The backlight may comprise an LED, light conditionfilms, and mirrored reflection surface to direct the light towards thedisplay. If an OLED micro-display is used, no backlight is required. Afirst lens 50 and a second lens 54 are also attached to the body 14. Afirst LED reflective surface 58 and a second LED reflective surface 62is also attached to the body 14. The reflective surface 62 may be alightpipe. A mirrored film, a mirrored coating, or a thin first surfacemirror can be used. A nose pad 66 is also attached to the body 14.Located adjacent to the first micro display 34 is a first lightprocessing film 74. Located adjacent to the second micro display 38 is asecond light processing film 78. The disclosed invention may use, but isnot limited to, the following light processing film: Vikuiti displayfilms by 3M are used. The binocular display 10 is configured such that auser looking into the first (left) and second (right) lenses 50, 54, hisview will follow a light path and he will see an image of the microdisplay. The light path is shown as line 82. Angle Ø is minimized, thegeometry of the system tending to force the micro-display towards thenose and face. The minimized angle Ø is about 79° in the embodimentshown. The angle Ø may range from about 59° to about 89°. Minimizedoptical reflection path angles results in a folded optical system thatmoves the micro-displays towards the nose and face. This appearsundesirable until the optical path is constrained in length and a morecompact system results. The optical path length is minimizedsufficiently to create space for a nose cavity so that system can beworn close to the face at a comfortable view height. The optical pathlength is about 25 mm in the embodiment shown. The optical path may varyfrom about 15 mm to about 45 mm. The binocular display 10 may also havea connector member 86, designed to allow the binocular display 10 to“snap”, attach, or otherwise connect to a pair of eyeglasses, goggles,helmet, or other wearable device that allows a user to position thebinocular display 10 to allow the user to look through the first andsecond lenses 50, 54. Due to the novel design of the disclosed binoculardisplay 10, the depth D of the display 10 is minimized, and is less thanabout 8 mm to about 40 mm, and preferably about 19 mm.

FIG. 2 shows a side perspective view one embodiment of an eyeglass frame90 that has a frame connector member 94 designed to connect with or tothe connector member 86 of the binocular display 10. The binoculardisplay 10 is shown in an unattached arrangement with respect to theframes 90. In the shown embodiment, the binocular display has anoptional first housing 98, and optional second housing 102 attached tothe body 14 for housing optional ear bud wires 106 as shown, and anoptional video/power cable 110. The first and second housings 98, 102may provide strain relief to the wires 106 and cable 110. Strain reliefis a length of flexible material added at the plug and product end of acable to create a more gradual cable bend and control cable location fordecreasing cable damage. FIG. 3 shows a top perspective view of theembodiment from FIG. 2.

FIG. 4 is a top perspective exploded view of the binocular display 10.In this view, the body 14 comprises a top cover 114. The second microdisplay 38 and second light processing film 78 is shown in an explodedconfiguration. A printed circuit board assembly (PCBA) 118 is shown inthis view. When the binocular display is assembled, the PCBA 118 is incommunication with both the first and second micro displays 34, 38. Inaddition, the optional ear bud wires 106 and video/power cable 110 arealso in communication with the PCBA 118.

FIG. 5 shows a bottom perspective view of the disclosed binoculardisplay 10. In this view a first display adjustment cap 122 that isremoveably attachable to, and is shown removed from a first displayadjustment orifice 126 in the bottom surface of the body 14. Locatedwithin the body 14, and accessible through the first display orifice 126is a first adjustment element 130, which allows for adjustment of themicro display. These adjustments may be made during manufacturing toaccount for location tolerances. In other embodiments, adjustments maybe made later by a technician or user. Similarly, there is a seconddisplay adjustment cap 134, which covers and removeably attaches to asecond display adjustment orifice. Located within the body, andaccessible through the second display adjustment orifice is a secondadjustment element. The adjustment element may be used for adjustmentduring manufacturing.

FIG. 6 shows a top view of the disclosed binocular micro display system12 being worn by a user 138. The system 12 comprises the binoculardisplay 10 and eyeglass frames 90. The center mounting of the binoculardisplay 10 to the eyeglass frames 90 via the connector member 86 andframe connector member 94, prevents flexing of the frames fromdistorting the optical alignment of the of the micro displays 34, 38with respect to the lenses 50, 54.

FIG. 7 is a right rear perspective view of the disclosed binocular microdisplay system 12, with the optional first and second housings 98, 102.FIG. 8 is a front perspective view of the disclosed binocular microdisplay system 12, with the optional first and second housings 98, 102.

FIG. 9 is a close-up partially exploded view of the housing 14, lenses50, 54, and micro displays 34, 38. In this view a first lens housing 142is shown, housing the first lens 50, first mirror 18, and an optionalthird lens 146. A first lens housing cover 150 is removeably attachableto the first lens housing 142. A first optical subassembly 166 iscomprised by the first lens housing 142 and first lens housing cover150. The first optical subassembly 166 is housed within the housing 14.A second optical subassembly 170 is similarly comprised by a second lenshousing 154 and second lens housing cover 158. The second lens housing154 houses an optional fourth lens 162 and the second mirror 22 (notvisible in this view). An electronic subassembly 174 comprises anelectronics housing 178, and an electronics cover 182. The second microdisplay 38 is housed within a second micro display subassembly 190. Thefirst micro display 34 is not visible, but the first micro displaysubassembly 186, which it is housed in, is visible within theelectronics housing 178. A first backlight lightpipe 194 is shownremoved from the electronics housing 178. A second backlight lightpipe198 is shown housed within the electronics housing 178 and in visiblecommunication with the second backlight 46 (in this embodiment a secondLED). As shown, the first backlight lightpipe 194 has been removed fromthe electronics housing 178, and the first micro display subassembly 186has been reinstalled into the electronics housing assembly 178. However,when the binocular display 10 is in operation, the first backlight lightpipe 194 is positioned generally underneath the first micro displayassembly 186, and in visible communication with the first backlight 42,and the first micro display 34. Similarly, when the binocular display 10is in operation, the second backlight lightpipe 198 is positionedgenerally underneath the second micro display assembly 190, and invisible communication with the second backlight 46, and the second microdisplay 38.

FIG. 10 is schematic view of the optical path elements of the disclosedbinocular display 10. A user's left eye 202 and right eye 206 are shownfor reference. A user's left eye 202 optical path is shown by the line210, and a user's right eye 206 optical path is shown by the line 214.Please note that in this embodiment a first front polarizer 218 and afirst rear polarizer 222 are located along the optical path 210 oneither side of the first micro display 34. Similarly, also in thisembodiment a second front polarizer 226 and a second rear polarizer 230are located along the optical path 214 on either side of the secondmicro display 38. One of the novel aspects of this disclosed binoculardisplay 10, is that arrangement of elements shown in FIG. 10 are suchthat the angle Ø is optimized so that the depth D dimension of thebinocular display is minimized. The angle Ø may range from about 69° toabout 89°, and preferably may be about 84°, and the D dimension mayrange from about 8 mm to about 40 mm, and preferably be about 23 mm.Please note that the distance at which the left and right eye anglesconverge and optical focal distance determine the virtual distance atwhich the display image appears to the user.

FIG. 11 shows a front view of the disclosed binocular micro displaysystem 12. The compact size of the binocular display 10 allows it tomount behind the eyeglass frame 90, and not be readily seen by others.FIG. 12 is front view of the disclosed binocular micro display system12. In this view, it can be seen that the lenses 50, 54, and thebinocular display 10 only occlude a small percentage of the totalvisible portion of the eyeglasses. The system shown occludes about 33percent of the user's view which varies based on the distance worn fromthe eyes, and may vary from about 10% to about 50% occlusion.

FIG. 13 shows a top perspective of the binocular micro display system12. In this view details of the connector members 86, 94 are shown. Inthis embodiment, the connector member 86 has a generally dovetail shapethat slides into a generally dovetail shaped receptacle 94. A mount lock234, sliding mount swivels 238, and a mount lock connector 242, alongwith the connector member 86 and generally dovetail shaped receptacle 94make up one embodiment of the disclosed mounting system that allows formounting of the binocular display 10 into an eyeglass frame 90. Ofcourse, the connector members 86, 94 may comprise any other suitableconnection means, including, but not limited to: screws, quick releaseattachment members; buttons; and snaps. FIG. 14 is a top cross-sectionalclose up view of the mounting system.

The binocular display invention has an independent housing structurejoining the left and right optics. The binocular micro display systemutilizes a center mount (86, 94) located on the independent housingstructure and the eyeglasses frame that minimizes moment loading on thebinocular optics and eliminates distortion of the alignment of theoptics and micro displays that can result from user forces on theglasses without this invention. The electrical connections from theinvention to the eyeglass frames or other devises are made within thecenter mount area. The center mount area includes the front, top,bottom, and rear surfaces of the independent bridge structure betweenthe left and right eye lens. The center mount features for sunglassesare located on the front of the independent bridge structure. The centermount invention gives the devise the flexibility to mount behindsunglasses, glasses, goggles, helmet visors, or any devise that canbenefit from minimal occlusion around the binocular display field ofview. In this document, the term eyeglasses frame shall mean to include:sunglasses, prescription eyeglasses, safety glasses, goggles, and helmetvisors. The narrow center mount is what allows the bridge structure ofthe invention to be independent and creates a smaller and lighterembodiment of the invention and a viewing experience that is unaffectedby typical forces to the device from users.

The center mount invention allows the binocular display system to beeasily adjusted for pitch rotation and vertical height to the mountingdevise and also the nose pads. This allows the optics to be adjusted toaccommodate different users and allows the user to select verticalviewing height that is most comfortable to them. The optics can also beadjusted to be above the primary view of the user. The attributes of theinvention allow the unit to easily mount behind many custom glasses andsunglasses. These custom glasses and sunglasses can house batteries,additional PCBAs, and also carry headphone or ear bud speakers.

The compact size of the unit allowed the invention of a binoculardisplay system easily changed by the user to mount behind other pairs ofsunglasses of desired style and attributes while maintaining significantsituation awareness for the user. This quick user change inventionfurther overcomes the esthetic problem of previous head mounted displaysthat mount outside or are housed within supporting devises.

Assembly

The invention should be viewed as a whole with locations for the optics,mirrors, and displays producing the compact system that is placed behindsunglasses or glasses. The left and right optical path of the inventionconsists of an eye lens or doublet, air gap, mirror, air gap, secondlens or doublet, air gap, polarizer (see FIG. 10), micro display (seeFIGS. 9 and 10), polarizer, and backlight. The backlight can be madecommon between the left and right system. The second lens or doublet inthe optical path maybe used in embodiments of the invention where thespecific micro display and field of view require such a lens or doublet.

The invention sets the incident to reflected angle of the optical pathat the mirror to an optimized value to make the invention the minimumsize given the specific sizes of the optical path elements in thespecific embodiment of the invention. Optimizing the optical path angleØ at the mirror reduces the distance the outer ends of the mirrorprotrude forward. The optimized optical path angle Ø points the opticalpath into the users face and nose so the invention minimizes the pathlength to avoid fit problems. Minimizing the optical path length (asshown by the lines 210, 214) brings the mirror, lens, and displays closeto intersecting in a small triangle.

The invention minimizes the length of the optical path sufficiently toallow a nose cavity. The nose cavity is at least partially between theleft and right optical paths so the unit may fit close to the face. Oneor more printed circuit boards (PCB) are located in the independentcenter structure.

The uniqueness of the configuration of the invention allows the specificembodiment of components in the optical path to be changed withoutaltering the intents of the invention. This may include the addition orelimination of optical path components or air gaps.

Replacing a LCD micro displays with OLED micro displays in otherembodiments of the invention eliminates the need for a backlight. AnOLED embodiment further enhances the size reducing advantages of theinvention. Future micro display technologies may also be deployed in theinvention.

Optical Alignment

The image alignment, focus, position, and distance of the left and rightoptical micro display system have sufficient correspondence to avoiddisorientation, or eye strain for the user. The elements in the opticalpath are precisely located in the invention. To assure reliable highquality the position tolerance in the system may be accounted for by oneof the following non-limiting assembly adjustment inventions:

In one embodiment of this invention the eye lens, mirror, and secondlens (if any) form a left and right optical subassembly. The displays,polarizers, backlight, PCB, and center bridge structure form anelectronic display subassembly. The width of this electronic displaysubassembly is chosen based on the nominal interpupillary distancedesired. A calibrated fixture adjusts the positions of the optical andelectronic display subassemblies relative to each other in all axes ofrotation and translation until the desired correspondence of left andright eye image alignment, focus, position, and distance is achieved.The subassemblies are rigidly secured prior to removal from the fixture.

In one embodiment of this invention, all components of the left andright optical path are positioned in an assembly structure with theexception of the mirrors. The position and rotation of the mirrors areadjusted with high precision in a calibrated fixture until the desiredcorrespondence of left and right eye image alignment, focus, position,and distance is achieved. The mirrors are rigidly secured prior toremoval from the fixture.

In one embodiment of this invention, the unit is assembled withoutsecuring the position of the micro-display subassemblies. The unit isplaced in a fixture and the micro-displays are grasped through smallopenings. The displays are adjusted relative to each other in all axesof rotation and translation until the desired correspondence of left andright eye image alignment, focus, position, and distance is achieved.The subassemblies are rigidly secured prior to removal from the fixture.
